12、ContentsANSI/AMCA 540-13 | 1Test Method for Louvers Impacted by Wind Borne Debris1. PurposeThe purpose of this standard is to establish uniform meth-ods for laboratory testing of louvers that are impact tested with the large missile described in ASTM E 1996-04 1 and E 1886-05 2.2. ScopeThe scope of
13、this standard is for impact testing of louvers used on the outside of buildings as required by the ICC International Building Code 3 and the ICC International Residential Code 4.The following precautionary statement pertains only to the test method portion, Section 5, of this specification: This sta
14、ndard does not purport to address all of the safety con-cerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of the regu-latory limitations prior to use.3. Definitions3.1 Enh
15、anced protection (Essential Facilities) Buildings and other structures designated as essential facil-ities, including, but not limited to, hospitals; other health care facilities having emergency treatment facilities; jails and detention facilities; fire, rescue and police stations, and emergency ve
16、hicle garages; designated emergency shel-ters; communication centers and other facilities required for emergency response; power generating stations; other public utility facilities required in an emergency; and build-ings and other structures having critical national defense functions.3.2 Basic pro
17、tection Any building or structure that is not an Essential Facility as described in Section 3.1.3.3 Horizontal/vertical-bladed louverLouvers shall be designated horizontal or vertical-bladed based on the orientation of the blades on the front or exteri-or side of the louver.3.4 SpecimenA louver asse
18、mbly for testing consisting of one or more lou-ver sections.3.5 Louver SectionA single louver panel. Panels can (but are not required to) be connected to each other to make up larger assemblies for testing purposes. For example, a 2-section wide louver assembly is two panels wide.4. Test Specimens4.
19、1 Number of specimens4.1.1Per ASTM E 1996-04 and ASTM E 1886-05, a minimum of three sections shall be impacted. This requirement may be satisfied by testing one single-section and one multi-section unit or by testing three identical single-section units.4.1.2 One additional specimen may be submitted
20、 for testing should any original submitted specimen described in Section 4.1 fail any portion of the AMCA Standard 540 testing. This is described in Section 9.2. If all specimens pass the AMCA Standard 540, and then some or all of the same specimens are then subjected to Cyclic testing as described
21、in Section 8, and any one specimen fails any portion of the subsequent test(s), then one additional specimen may be submitted to re-test to the subsequent tests as long as the additional specimen first passes the AMCA Standard 540 tests.4.2 Size of specimensThe test specimen selected is intended to
22、evaluate the criti-cal failure area of the louver and provide guidance for blade support requirements. The critical failure area for louvers is the connection between the louver blade end and the perim-eter louver frame. Failures in this area result in loose mate-rial that can result in projectiles
23、in high wind events. The most stringent test specimen for this connection is a section where the blade has no additional support between these end connections. Energy from the impact is transferred to the connection with little absorption by blade flexure. This test specimen also provides guidance r
24、egarding the maxi-mum unsupported blade length that will not allow the projec-tile to pass through the louver blades. Louvers manufactured with blade spans greater than that of the test specimen shall have blade supports at a spacing that matches the tested specimen blade length. These supports are
25、typically locat-ed behind the blade running perpendicular to the axis of the blade and are attached to the perimeter frame of the louver or to the surrounding building structure. Due to the fact that the test specimen is used to qualify support locations in this way, the manufacturer may wish to tes
26、t an additional speci-men with a width narrower than desirable support spacing to establish a smaller minimum section width.2 | ANSI/AMCA 540-13The size of the test specimen shall be as defined in Section 4.2.1.1, 4.2.1.2, 4.2.1.3, or 4.2.1.4.4.2.1 Single section louver qualification4.2.1.1 Horizont
27、al bladeThe test specimen shall consist of a single section. The sec-tion width shall be equal to the maximum blade span the manufacturer would supply without providing a blade sup-port plus the added width of the specimen jamb frames. The minimum height of the test specimen shall be 915 mm (36 in.)
28、. The test specimen shall also contain a minimum of five blades. This specimen shall qualify single sections of widths greater than the specimen, provided the manufac-turer supports the louver blades at a spacing equal to the blade length of the specimen. The tested width becomes the minimum section
29、 certified by the impact test. The spec-imen qualifies all single section heights. If the manufactur-er wishes to certify a width narrower than the test specimen, an additional test specimen shall be provided. The minimum height of this narrower test specimen shall also be 915 mm (36 in.), and it sh
30、all contain a minimum of five blades. See Annex A, Figure A.1.4.2.1.2 Vertical bladeThe test specimen shall consist of a single section. The sec-tion height shall be equal to the maximum blade span the manufacturer would supply without providing a blade sup-port plus the added thickness of the speci
31、men head and sill frames. The minimum width of the test specimen shall be 36 inches. The test sample shall also contain a minimum of five blades. This specimen shall qualify single sections of heights greater than the specimen, provided the manufac-turer supports the louver blades at a spacing equal
32、 to the blade length of the specimen. The tested height becomes the minimum section certified by the impact test. The spec-imen qualifies all single section widths. If the manufactur-er wishes to certify a height less than the test specimen, an additional test specimen shall be provided. The minimum
33、 width of this smaller test specimen shall also be 915 mm (36 in.), and it shall contain a minimum of five blades. See Annex A, Figure A.2.4.2.2 Multi-section louver qualification4.2.2.1 Horizontal bladeThe test specimen shall consist of a minimum of two sec-tions. Each section width shall be equal
34、to the maximum blade span the manufacturer would supply without providing a blade support plus the added width of the specimen jamb frames. The height of the louver specimen shall be equal to the maximum height the manufacturer desires to be certified as impact resistant, or the maximum height allow
35、ed by the testing facility (rotation of the test sample 90 is permissi-ble to overcome lab width/height limitations). This specimen shall qualify sections of widths greater than the specimen sections, provided the manufacturer supports the louver blades at a spacing equal to the blade length of the
36、spec-imen. The multi-section minimum allowable width shall be based upon one of the following tests: The multi-section sample described in this section The narrowest single section tested sample A narrow multi-section sampleSee Annex A, Figure A.3.4.2.2.2 Vertical bladeThe test specimen shall consis
37、t of a minimum of two sec-tions. Each section height shall be equal to the maximum blade span the manufacturer would supply without provid-ing a blade support plus the added thickness of the spec-imen head and sill frames. The width of the louver speci-men shall be equal to the maximum width the man
38、ufacturer desires to be certified as impact resistant, or the maximum width allowed by the testing facility (rotation of the test sam-ple 90 is permissible to overcome lab width/height limita-tions). This specimen shall qualify sections of heights great-er than the specimen sections, provided the ma
39、nufacturer supports the louver blades at a spacing equal to the blade length of the specimen.The multi-section minimum allowable height shall be based upon one of the following tests: The multi-section sample described in this section The smallest single section tested sample A smaller multi-section
40、 sample with a shorter blade lengthSee Annex A, Figure A.4.4.2.2.3Testing of a multi-section louver shall also qualify a single section louver to the same blade span as the tested multi-section louver. Each connection joint design needs to be tested.5. Test Methods5.1 SpecimensThe specimens shall be
41、 tested according to test meth-od, ASTM E1886-05, for large-missile impact testing only, and with taking exception to ASTM E1886-05 Section 8.2 regarding required size for testing and Section 11.1 regard-ing specimen mounting anchors to the test frame.5.2 MissileDetermine the missile based upon buil
42、ding classification according to Section 6.ANSI/AMCA 540-13 | 35.3 Locations of impact5.3.1 Single section impact locationsThe initial contact between the missile and louver shall be in such a way that: the entire leading face of the missile shall impact within a 222 mm (8.75 in.) diameter tolerance
43、 circle; and any portion of the leading face of the missile shall impact the exterior most edge or plane of the targeted blade. The plane of the tolerance circle shall be on the same plane as the impacted face of the louver with the center of the cir-cle at the targeted location as described in Sect
44、ion 5.3.1.1 or 5.3.1.2. See Figure 4. Once the leading face of the mis-sile passes through the tolerance circle, it is permissible for the missile to make contact with the louver blades outside of the tolerance circle.If the exterior most part of the targeted blade is a plane (vs. an edge), then the
45、 targeted location is adjusted after com-plying with Section 5.3.1.1 or 5.3.1.2 so that the targeted location is centered on the front plane of the blade. See Figure 4.5.3.1.1 Horizontal blade impact locationsImpact each louver section three times as shown in Figure 1.The first impact location shall
46、 be targeted on the front edge/surface of a blade closest to a point: 152 mm (6 in.) from the plane of the cut end of the louver blade;and 152 mm (6 in.) from the front interior edge of the sill. The impact shall not contact the jamb or sill frame.The second impact location shall be targeted at the
47、mid-span of a center blade on the front edge/surface of the blade.The third impact location shall be targeted on the front edge/surface of a blade closest to a point: 152 mm (6 in.) from the plane of the cut end of the louver blade;and 152 mm (6 in.) from the front interior edge of the head. This th
48、ird impact shall be adjacent to the jamb that is oppo-site of the jamb closest to the first impact. The impact shall not contact the jamb or head frame.5.3.1.2 Vertical blade impact locationsImpact each louver three times as shown in Figure 2.The first impact location shall be targeted on the front
49、edge/surface of a blade closest to a point: 152 mm (6 in.) from the plane of the cut end of the louver blade;and 152 mm (6 in.) from the front interior edge of the jamb. The impact shall not contact the jamb or sill frame.The second impact location shall be targeted at the mid-span of a center blade on the front edge/surface of the blade.The third impact location shall be targeted on the front edge/surface of a blade closest to a point: 152 mm (6 in.) from the plane of the cut end of the louver blade;and 152 mm (6 in.) from the front interior edge of the jamb
